Resource scheduling method, apparatus, and device

A resource scheduling apparatus, comprising: a processor; a transmitter; memory connected to the processor and including instructions that cause the apparatus to generate resource scheduling information for a frequency domain resource on the basis of a plurality of predefined resource units (RUs) of a frequency domain resource, the resource scheduling information indicating information related to the number of stations scheduled on each RU and an identifier of each scheduled station, an allocation of one or more RUs for the frequency domain resource, the allocation comprising: size of each RU, the size indicating a quantity of subcarriers included in an allocated RU; and location of each RU, the location indicating where the corresponding quantity of subcarriers are located within a bandwidth of the frequency domain resource; the transmitter being configured to transmit the resource scheduling information; for which a smallest size of a resource unit that supports MU-MIMO is predefined such that: for a first RU in the allocation, which first RU is smaller than the predefined smallest size for MU-MIMO, the number of one or more stations scheduled on the first RU is a default value; for a second RU in the allocation, which second RU is not smaller than the predefined smallest size for MU-MIMO, at least 2 bits are used for indicating the number of the one or more stations scheduled on the second RU.

A resource scheduling apparatus, comprising: a processor; a receiver connected to the processor; and memory connected to the processor, the receiver being configured to receive resource scheduling information indicating information related to the number of stations scheduled on each RU and an identifier of each scheduled station, an allocation of one or more RUs for a frequency domain resource, the allocation comprising: size of each RU, the size indicating a quantity of subcarriers included in an allocated RU; and location of each RU, the location indicating where the corresponding quantity of subcarriers are located within a bandwidth of the frequency domain resource; the memory including instructions that, when executed by the processor, cause the apparatus to determine, based on a plurality of predefined RUs of the frequency domain resource, and according to the received resource scheduling information, the one or more allocated RUs and corresponding scheduled stations; for which a smallest size of a resource unit that supports MU-MIMO is predefined such that: for a first RU in the allocation, which first RU is smaller than the smallest size for MU-MIMO, the number of one or more stations scheduled on the first resource unit is a default value; for a second RU in the allocation, which second RU is greater than the smallest size for MU-MIMO, at least 2 bits are used for indicating the number of the one or more stations scheduled on the second resource unit.

A resource scheduling method, comprising: generating, by a communication apparatus in a WLAN, resource scheduling information for a frequency domain resource on the basis of a plurality of predefined resource units of a frequency domain resource, the resource scheduling information indicating information related to the number of stations scheduled on each RU and an identifier of each scheduled station, an allocation of one or more RUs for the frequency domain resource, the allocation comprising: size of each RU, the size indicating a quantity of subcarriers included in an allocated RU; and location of each RU, the location indicating where the corresponding quantity of subcarriers are located within a bandwidth of the frequency domain resource; and sending, by the communication apparatus, the resource scheduling information; for which a smallest size of a resource unit that supports MU-MIMO is predefined such that: for a first RU in the allocation, which first RU is smaller than the smallest size for MU-MIMO, the number of one or more stations scheduled on the first RU is a default value; for a second RU in the allocation, which second RU is not smaller than the smallest size for MU-MIMO, at least 2 bits are used for indicating the number of the one or more stations scheduled on the second RU.

A resource scheduling method, comprising: receiving, by a communication apparatus in a WLAN, resource scheduling information, the resource scheduling information indicating information related to the number of stations scheduled on each RU and an identifier of each scheduled station, an allocation of one or more RUs for the frequency domain resource, the allocation comprising: size of each RU, the size indicating a quantity of subcarriers included in an allocated RU; and location of each RU, the location indicating where the corresponding quantity of subcarriers are located within a bandwidth of the frequency domain resource; and determining, by the communication apparatus, based on a plurality of predefined resource units of the frequency domain resource, and according to the received resource scheduling information, the one or more allocated RUs and the corresponding one or more scheduled stations for which a smallest size of a resource unit that supports MU-MIMO is predefined such that: for a first RU in the allocation, which first RU is smaller than the smallest size for MU-MIMO, the number of one or more stations scheduled on the first RU is a default value; for a second RU in the allocation, which second RU is not smaller than the smallest size for MU-MIMO, at least 2 bits are used for indicating the number of the one or more stations scheduled on the second RU.
